72251L10JG

Overview

The Renesas Electronics Corporation 72251L10JG is a synchronous First-In, First-Out (FIFO) memory device belonging to the 7200 series. It provides a storage capacity of 72K organized as 8K words by 9 bits. The component supports unidirectional data transfer with a maximum clock frequency of 66.7MHz and features a typical access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 50mA. The device is housed in a 32-PLCC surface-mount package and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Synchronous FIFO architecture with independent read and write clocks for flexible data buffering
• Programmable full and empty flags to indicate memory status
• Unidirectional bus configuration for dedicated data flow applications

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify component authenticity through authorized distributors or official Renesas channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for specific packaging variations such as tube quantities. Ensure the lead-free designation matches project requirements. Validate that the PLCC-32 footprint aligns with existing PCB designs.

Selection Notes

Select this component when a synchronous FIFO with 8x9 organization and 10ns speed is required. Consider the 32-PLCC package for surface mount compatibility. Evaluate power consumption against system limits given the 50mA maximum current draw. Verify temperature range suitability for the intended environment. Compare against other 7200 series variants if different speeds or capacities are needed.

Part Context

This part belongs to the Renesas 7200 series of high-speed synchronous FIFOs. These devices are designed for high-performance data buffering applications requiring precise timing control. The series offers various configurations in terms of depth, width, and speed grades. The 72251 variant specifically targets applications needing moderate density with fast access times.

Replacement Considerations

Check for direct pin-compatible substitutes within the 7200 series offering similar speed and capacity. Verify electrical characteristics match original specifications. Confirm package type remains identical to avoid PCB redesign.
